I use a copper based joint compound and I am also not worried about
corrosion. I have a lot of ground rods spread 50+ feet out from my towers
and my clamps are buried. It would be a major trip / lawnmower hazard if
they stuck up out of the ground. I suppose that you could have the
connection below the ground using one of those plumbing enclosures however
I have never seen a joint loosen.

First, I wouldn't worry about a few microns of corrosion, especially
when lightning is concerned. A lightning bolt has already traveled
thousands of feet through an insulator (air) - another thousandth of
an inch of corrosion is nothing.
Second, as someone pointed out, the clamp itself should not be buried,
for two reasons. One to reduce corrosion and two, to permit
inspection.
